Automobile calibration device

ABSTRACT

The present invention relates to the field of automobile maintenance and device calibration technologies, and discloses a clamping apparatus and an automobile calibration device. The clamping apparatus includes a fixing plate, a fixing block and a tension knob. The fixing block includes a fixing block body and a locking spring piece. The fixing block body is installed on the fixing plate. A receiving cavity is enclosed by the fixing block body and the fixing plate. The locking spring piece is located in the receiving cavity. The tension knob is installed on the fixing block body. The tension knob is capable of rotating relative to the fixing block body, to extend inside the receiving cavity and to abut against the locking spring piece. When a to-be clamped and calibrated apparatus is inserted in the receiving cavity, the tension knob may push the locking spring piece to abut against the to-be clamped and calibrated apparatus. Because the locking spring piece is in surface contact with the to-be clamped and calibrated apparatus, a friction between the locking spring piece and the to-be clamped and calibrated apparatus increases, so that the locking spring piece may firmly abut against the to-be clamped and calibrated apparatus.

This application is a continuation of International Patent ApplicationNo. PCT/CN2019/083597 filed on Apr. 22, 2019, which claims priority toChinese Patent Application No. 201810362137.X filed on Apr. 20, 2018,both of which are incorporated by reference herein in their entireties.

BACKGROUND Technical Field

The present application relates to the field of automobile maintenanceand device calibration technologies, and in particular, to an automobilecalibration device having a clamping apparatus.

Related Art

In the field of automobile maintenance, for example, during calibrationof an advanced driver assistant system (ADAS), a calibration apparatusneeds to be installed on an automobile calibration device, to calibratein-vehicle assistance driving components, such as a camera.

For different automobile models or different calibration requirements,different calibration apparatuses need to be changed frequently, and thecalibration apparatuses need to be locked tightly and secured.Currently, common structures are locking by using a C-type snap ring andabutting tightly by rotating a screw. The two structures have thefollowing defects:

-   -   1. The C-type snap ring may slip, and is inconvenient to be        assembled due to a small gap during an assembly process.    -   2. In the manner of abutting tightly by using the screw, there        is only one fulcrum used for securing, which easily leads to a        location deviation. In addition, if the calibration apparatus is        an appearance component, the surface of the appearance component        is easily damaged.

The supporting member 21 is installed on the bracket apparatus 10and is movable in a vertical direction relative to the bracket apparatus10. The following trigger apparatus 3229 may also be directly installedon the supporting member 21. When the supporting member 21 moves in avertical direction, the trigger apparatus 3229 may trigger the followinglimit switch 3225.

The first driving mechanism 32 is an electric drive mechanism,configured to drive the elevating screw rod 31 to rotate around thecentral axis thereof. The first driving mechanism 32 includes a motorassembly 320, a control assembly 322 and a power supply assembly (notshown in the figure). The motor assembly 320 is configured to drive theelevating screw rod 31 to rotate around the central axis thereof. Thecontrol assembly 322 is configured to control the motor assembly 320 todrive the elevating screw rod 31 to rotate around the central axisthereof. The power supply assembly is configured to supply power for themotor assembly 320 and the control assembly 322.

The motor assembly 320 includes a motor 3200, a first timing pulley3202, a second timing pulley 3204 and a driving belt 3206. The motor3200 is fixedly installed on an upper surface of the installation plate1200. The motor 3200 is a stepping motor. It can be understood that, insome other embodiments, the motor 3200 may be another control motor suchas a servo motor. The first timing pulley 3202 is located in theinspection port 1208. The first timing pulley 3202 is fixedly installedon a rotating shaft of the motor 3200 and the first timing pulley 3202and the rotating shaft of the motor 3200 are coaxially disposed. One endof the elevating screw rod 31 passes through the second shaft base 312and the inspection port 1208. The second timing pulley 3204 is locatedin the inspection port 1208. The second timing pulley 3204 is fixedlyinstalled on the elevating screw rod 31 and the second timing pulley3204 and the elevating screw rod 31 are coaxially disposed. The firsttiming pulley 3202 and the second timing pulley 3204 are spaced by apreset distance. When the motor 3200 rotates, the first timing pulley3202 drives the second timing pulley 3204 to rotate by using the drivingbelt 3206, so that the elevating screw rod 31 rotates around the centralaxis thereof. When the motor 3200 rotates in a first rotationaldirection, the location adjusting apparatus 20 rises in a verticaldirection relative to the bracket apparatus 10; and when the motor 3200rotates in a second rotational direction, the location adjustingapparatus 20 falls in a vertical direction relative to the bracketapparatus 10. The first rotational direction and the second rotationaldirection are opposite.

The driving belt 3206 is sleeved on the first timing pulley 3202 and thesecond timing pulley 3204. When the first timing pulley 3202 rotates,the first timing pulley 3202 drives the second timing pulley 3204 torotate by using the driving belt 3206. A peripheral surface of the firsttiming pulley 3202 and a peripheral surface of the second timing pulley3204 are both provided with gear tooth. The driving belt 3206 includesan assembly surface 3207. The gear tooth of the first timing pulley 3202and the gear tooth of the second timing pulley 3204 are both in contactwith the assembly surface 3207. The assembly surface 3207 includes agear teeth area 3208 and a non-gear teeth area 3209. The gear teeth area3208 is provided with gear tooth. The gear teeth area 3208 may mesh andmate with the first timing pulley 3202 and the second timing pulley3204. The non-gear teeth area 3209 may be in contact with and mate withthe first timing pulley 3202 and the second timing pulley 3204. When themotor 3200 rotates and the gear teeth area 3208 meshes and mates withthe first timing pulley 3202, or the gear teeth area 3208 meshes andmates with the second timing pulley 3204, the first timing pulley 3202and the second timing pulley 3204 move synchronously, and a rate of thesecond timing pulley 3202 is a first preset rate value. When the motor3200 rotates and the first timing pulley 3202 and the second timingpulley 3204 are only in contact with and mate with the non-gear teetharea 3209, due to factors such as slipping, the non-gear teeth area 3209enables the first timing pulley 3202 and the second timing pulley 3204to move asynchronously, and the rate of the second timing pulley 3202 isa second preset rate value. The first preset rate value is greater thanthe second preset rate value. It should be noted that, by dividing thegear teeth area 3208 and the non-gear teeth area 3209 on the assemblysurface 3207, the rate of the second gear teeth 3204 is controlled whilea rate of the first gear teeth 3202 remains unchanged, to achieve thepurpose of deceleration.

Referring to FIG. 9 , the control assembly 322 includes a controller3220, an up key 3222, a down key 3224, a limit switch 3225 and a triggerapparatus 3229.

The trigger apparatus 3229 is a plate-shaped structure. The triggerapparatus 3229 is installed on the sliding member body 210 and thetrigger apparatus 3229 and the slider 312 are located on a same side ofthe sliding member body 210. The limit switch 3225 is installed on thevertical beams 1206. The limit switch 3225 is located above or below thetrigger apparatus 3229. The up key 3222 and the down key 3224 are bothinstalled on the roof beam 1204. The controller 3220 is installed on anupper surface of the installation plate 1200. The up key 3222, the downkey 3224 and the limit switch 3225 are all electrically connected to thecontroller 3220 by using a wire harness (not shown in the figure). Thewire harness is disposed inside the wiring groove structure and isconnected to the controller 3220 through the wiring port.

The controller 3220 includes a driver (not shown in the figure) and anelevating control plate (not shown in the figure). The elevating controlplate is connected to the driver. The driver is connected to the motor3200. The driver is configured to control the motor 3200, for example,control the start/stop, speed, steering of the motor 3200. The up key3222, the down key 3224, an upper limit switch 3226 and a lower limitswitch 3228 are all electrically connected to the elevating controlplate. The up key 3222, the down key 3224, the upper limit switch 3226and the lower limit switch 3228 are all configured to control theelevating control plate.

When the up key 3222 is triggered, the controller 3220 is configured tocontrol the motor 3200 to rotate in the first rotational direction. Whenthe down key 3222 is triggered, the controller 3220 is configured tocontrol the motor 3200 to rotate in the second rotational direction.When the up key 3222 and the down key 3224 are simultaneously triggered,the controller 3220 is configured to control the motor 3200 to stoprotating. It should be noted that, because the up key 3222 and the downkey 3224 need to be set together for easy operation, there is apossibility of misoperation. When the up key 3222 and the down key 3224are simultaneously triggered, the controller 3220 is configured tocontrol the motor 3200 to stop rotating, which can prevent the motor3200 from being damaged by short circuit.

When the limit switch 3225 is triggered, the controller 3220 isconfigured to control the motor 3200 to stop rotating and control themotor 3200 to rotate only in a preset direction, so that the triggerapparatus 3229 is away from the limit switch 3225.

It can be understood that, there may be one or two limit switches 3225.In this embodiment, the limit switch 3225 includes an upper limit switch3226 and a lower limit switch 3228. The upper limit switch 3226 and thelower limit switch 3228 are both installed on a same side of thevertical beam 1206. The upper limit switch 3226 is located above thetrigger apparatus 3229 and the lower limit switch 3228 is located belowthe trigger apparatus 3228.

When the upper limit switch 3226 is triggered, the controller 3220 isconfigured to control the motor 3200 to stop rotating and control themotor 3200 to rotate only in the second rotational direction. When thelower limit switch 3228 is triggered, the controller 3220 is configuredto control the motor 3200 to stop rotating and control the motor torotate only in the first rotational direction. It should be noted that,by setting the upper limit switch 3226 and the lower limit switch 3228,the location adjusting apparatus 20 is automatically prevented fromexceeding the maximum stroke without manual intervention, and the motor3200 is set to rotate in a specified direction to prevent the motor 3200from being damaged by short circuit caused by misoperation.

The controller 3220 is further configured to control the rate of themotor 3200 increasing from 0 linear or non-linear to a preset value atthe moment when the motor 3200 starts to rotate.

The power supply assembly includes a DC base, a power switch and a powerindicator. When the DC base is connected to a power adapter and thepower switch is opened, the power indicator emits preset light, such asred light, and the controller 3220 and the motor 3200 may work.

Referring to FIG. 10 , the second driving mechanism 33 is a manualdriving mechanism. The second driving mechanism 33 includes a firsthelical gear 330, a second helical gear 332 and an elevating hand wheel334. A connecting rod (not shown in the figure) of the elevating handwheel 334 passes through the roof beam 1204 and is received in the firstshaft base 3100. The first helical gear 330 and the second helical gear332 are both located in the first shaft base 3100. The first helicalgear 330 is fixedly installed on the elevating screw rod 31 and thefirst helical gear 330 and the elevating screw rod 31 are coaxiallydisposed. The second helical gear 332 is fixedly installed on theconnecting rod of the elevating hand wheel 334 and the second helicalgear 332 and the connecting rod of the elevating hand wheel 334 arecoaxially disposed. The first helical gear 330 meshes with the secondhelical gear 332. A rotational axis of the elevating hand wheel 334 ishorizontally disposed. It should be noted that, by setting the seconddriving mechanism 33, in one aspect, the automobile calibration device100 may be used normally in a status of lacking of power supply. Inanother aspect, the first driving mechanism 32 and the second drivingmechanism 33 share one transmission mechanism 31, resulting in a compactoverall structure. It can be understood that, in some other embodiments,the angle between the rotational axis of the elevating hand wheel 334and the horizontal plane may be set to any value according to an actualsituation.

In this embodiment, the automobile calibration device 100 may implementautomatic rising and falling of the location adjusting apparatus 20, theclamping apparatus 40, the sliding apparatus 50 and the scale apparatus60 by setting the driving mechanism 30, to avoid manual adjustment.

In addition, the transmission mechanism 31 is set as the cooperationbetween the elevating screw rod 31 and the threaded through hole 2120.In the process of lifting the location adjusting apparatus 20, thelocation adjusting apparatus 20 may rise and fall gently and theposition adjusting apparatus 20 is uneasy to slide.

Moreover, by setting the first driving mechanism 32 and the seconddriving mechanism 33 to be used in the status of lacking of powersupply, the applicability of the automobile calibration device 100 isimproved. At the same time, the first driving mechanism 32 and thesecond driving mechanism 33 share the same transmission mechanism 31,thereby improving the overall compactness of the automobile calibrationdevice 100.

Finally, by dividing the gear teeth area 3208 and the non-gear teetharea 3209 on the assembly surface 3207, the rate of the second gearteeth 3204 is controlled to achieve the purpose of deceleration.

Referring to FIG. 11 and FIG. 12 together, the clamping apparatus 40includes a fixing block 41, a fixing plate 42 and a tension knob 43. Thefixing block 41 is fixedly installed on the fixing plate 42. A receivingcavity 44 is enclosed by the fixing block 41 and the fixing plate 42.The receiving cavity 44 is configured to receive a fixing rod of acalibration apparatus. The tension knob 43 is installed on the fixingblock 41. The tension knob 43 may rotate relative to the fixing block 41to extend inside the receiving cavity 44 and to abut against the fixingrod of the calibration apparatus inserted in the receiving cavity 44.

Referring to FIG. 13 , the fixing block 41 includes a fixing block body410 and a locking spring piece 412 and a magnetic element 414. Thefixing block body 410 is fixedly installed on the fixing plate 41 andthe receiving cavity 44 is enclosed by the fixing block body 410 and thefixing plate 42. The locking spring piece 412 is located in thereceiving cavity 44 and is configured to be pushed by the tension knob43 to abut against the fixing rod of the calibration apparatus. Themagnetic element 414 is fixedly installed on the fixing block body 410.The magnetic element 414 is located in the receiving cavity 44. Themagnetic element 414 is configured to absorb the locking spring piece412, so that the locking spring piece 412 is away from the fixing rod ofthe calibration apparatus. In this embodiment, there are two magneticelements 414, which are arranged in a vertical direction. The twomagnetic elements 414 are respectively located on two opposite ends ofthe locking spring piece 412, so that the locking spring piece 412 maybe strongly and stably absorbed. It can be understood that, in someother embodiments, the quantity of the magnetic elements 414 may bechanged according to an actual demand, provided that there is at leastone magnetic element 414.

Referring to FIG. 14 and FIG. 15 together, the fixing block body 410includes a side wall 4100, a bottom wall 4101 and a connecting wall4102. The bottom wall 4101 connects the side wall 4100 and theconnecting wall 4102. There are two connecting walls 4102, which areconnected to two opposite sides of the side wall 4100. Similarly, thetwo connecting walls 4102 are connected to two opposite sides of thebottom wall 4101. The two connecting walls 4102 and the bottom wall 4101are fixedly installed on the fixing plate 42. The side wall 4100, thebottom wall 4101, the connecting wall 4102 and the fixing plate 42jointly enclose the receiving cavity 44.

The side wall 4100 is provided with a groove 4104. The groove 4104 isconfigured to receive the locking spring piece 412. An inner wall of thegroove 4104 is provided with a threaded fixing through hole 4106 and areceiving groove 4108. The fixing through hole 4106 is a threaded holeand is configured to mate with the tension knob 43. The receiving groove4108 is a blind hole and there are two receiving grooves 4108, which areconfigured to receive the magnetic elements 414. The two receivinggrooves 4108 are arranged in a vertical direction and are respectivelylocated on two sides of the fixing through hole 4106.

One side of the side wall 4100 close to the bottom wall 4101 isperpendicularly connected to the bottom wall 4101, and the other side ofthe side wall 4100 away from the bottom wall 4101 inclines in adirection away from the receiving cavity 44, so that the other side ofthe side wall 4100 away from the bottom wall 4101 is at an obtuse angleto the bottom wall 4101. A width B of the other side of the connectingwall 4102 close to the bottom wall 4101 is less than a width A of oneside of the connecting wall 4102 away from the bottom wall 4101. Thatis, a width of a bottom of the receiving cavity 44 is less than a widthof a port of the receiving cavity 44, so that the fixing rod of thecalibration apparatus can be easily inserted in the receiving cavity 44.When the fixing rod of the calibration apparatus is inserted in thebottom of the receiving cavity 44, the fixing rod of the calibrationapparatus is firmly fixed in the receiving cavity 44.

Referring to FIG. 13 again, the fixing plate 42 is a rectangular plate,and may be made of stronger materials, such as a stainless steelmaterial.

The tension knob 43 includes a pushing rod 430 and a knob portion 432.The pushing rod 430 has an external thread and passes through the fixingthrough hole 4106, so that one end of the pushing rod 430 extends in thereceiving cavity 44. The pushing rod 430 mates with the fixing throughhole 4106 by threads. The knob portion 432 is cylindrical, is fixedlyinstalled on the other end of the pushing rod 430 and is configured tomake it convenient for the user to grip and rotate the tension knob 43.

In this embodiment, there are two the fixing blocks 41 and two tensionknobs 43. The two fixing blocks 41 are respectively fixedly installed onthe fixing plate 42, are located on a same side of the fixing plate 42,and are arranged in a horizontal direction.

Referring to FIG. 16 , when the knob portion 432 is rotated in acounterclockwise direction, the pushing rod 430 moves in a directionaway from the locking spring piece 412 and the pushing rod 430 is not incontact with the locking spring piece 412. In this case, the magneticelement 414 absorbs the locking spring piece 412 in a direction awayfrom the fixing plate 42, so that a size of the port of the receivingcavity 44 is increased, to facilitate insertion of the fixing rod 200.

Referring to FIG. 17 , when the fixing rod 200 is inserted in the bottomof the receiving cavity 44, the knob portion 432 is rotated in aclockwise direction, and the pushing rod 430 is in contact with thelocking spring piece 412 and pushes the locking spring piece 412 to abutagainst the fixing rod 200, so that the fixing rod 200 is clamped in thereceiving cavity 44.

In this embodiment, the locking spring piece 412 is pushed to abutagainst a clamping-needed apparatus such as the fixing rod 200 by usingthe tension knob 43. Because the locking spring piece 412 is in surfacecontact with the clamping-needed apparatus, friction between the lockingspring piece 412 and the clamping-needed apparatus is increased, so thatthe locking spring piece 412 can firmly abut against the clamping-neededapparatus. The assembly accuracy of the locking spring piece 412 and theclamping-needed apparatus is reduced, which is conducive to the quickassembly of the clamping-needed apparatus to the clamping apparatus 40.In addition, the locking spring piece 412 is absorbed in a directionaway from the fixing plate 42 by using the magnetic element 414, so thatthe size of the port of the receiving cavity 44 can be increased tofacilitate insertion of the clamping-needed apparatus.

Referring to FIG. 18 to FIG. 20 , the sliding apparatus 50 includes aguide rail 51, a sliding assembly 52 and a mounting assembly 53. Theguide rail 51 may be fixedly installed on the fixing plate 42 in anysuitable manner (for example, the guide rail 51 may be fixedly installedon the fixing plate 42 in a screw connecting manner) and is disposed ina horizontal direction. The sliding assembly may be movably installed onthe guide rail 51 and is slidable along the guide rail 51(alternatively, the sliding assembly 52 is movable in a horizontaldirection relative to the guide rail 51). The mounting assembly 53 isfixedly installed on the sliding assembly 52 and may follow the slidingassembly 52 to slide along the guide rail 51.

Specifically, referring to FIG. 21 , the guide rail 51 is roughly in acuboid shape and includes a first surface 510 and a second surface 512that are perpendicular to each other. The first surface 510 isperpendicular to the plane at which the fixing plate 42 is located. Thesecond surface 512 is parallel to the plane at which the fixing plate 42is located and faces away from the fixing plate 42. Particularly, inthis embodiment, the interior of the guide rail 51 is further providedwith a plurality of through holes 514 with a predetermined shape in ahorizontal direction and is configured to disperse the stress borne bythe interior of the guide rail 51. Also, in a case in which a rigidrequirement of the guide rail 51 is met, the weight of the guide rail 51is reduced. It can be understood that, in some other embodiments, thethrough holes 514 may also be omitted.

The first surface 510 is provided with a first sliding groove 5100configured to install the sliding assembly 52. The first sliding groove5100 extends in a horizontal direction. The cross section of the firstsliding groove 5100 is roughly in a “trapezoid shape”. A width of thebottom of the first sliding groove 5100 is less than a width close tothe opening, to reduce a friction area between the sliding assembly 52and the first sliding groove 5100, so that the sliding assembly 52 canslide along the first sliding groove 5100 more smoothly. Further, inthis embodiment, the opening of the first sliding groove 5100 is in a “Tshape” and is provided with first engagement portions 5102 extending toeach other, to limit the sliding assembly 52, reduce the shaking of thesliding assembly 52 and avoid the derailment of the sliding assembly 52.

In addition, the first surface 510 is further provided with a horizontalgraduated scale 5104 taking its center as the zero point and extendingto two sides. That is, the scale of the horizontal graduated scale 5104takes the center of the guide rail 51 as the zero point and graduallyincreases to two sides of the guide rail 51, to facilitate the positionlocating of the sliding assembly 52. It can be understood that, in someother embodiments, the horizontal graduated scale may also be disposedon the second surface 512, or the horizontal graduated scale 5104 isomitted,

The second surface 512 is provided with a second sliding groove 5120configured to install the sliding assembly 52. The second sliding groove5120 is parallel to the first sliding groove 5100. That is, the secondsliding groove 5120 also extends in a horizontal direction, so that thesliding assembly 52 is slidable along both the first sliding groove 5100and the second sliding groove 5120 and further moves in a horizontaldirection relative to the guide rail 51. Similarly, in this embodiment,the cross section of the second sliding groove 5120 is also roughly in a“trapezoid shape”. A width of the bottom of the second sliding groove5120 is less than a width close to the opening, to reduce a frictionarea between the sliding assembly 52 and the second sliding groove 5120,so that the sliding assembly 52 can slide along the second slidinggroove 5120 more smoothly. Further, in this embodiment, the opening ofthe second sliding groove 5120 is also in a “T shape” and is providedwith second engagement portions 5122 extending to each other, to limitthe sliding assembly 52, reduce the shaking of the sliding assembly 52and avoid the derailment of the sliding assembly 52.

In this embodiment, a width of the second surface 512 is greater than awidth of the first surface 510. Four second sliding grooves 5120 areincluded. The four second sliding grooves 5120 are parallel to thesecond surface 512 at intervals. Each second sliding groove 5120 may beconfigured to install the sliding assembly 52. It can be understoodthat, in some other embodiments, there may be more or fewer secondsliding grooves 5120 according to an actual demand. For example, thequantity of the second sliding grooves 5120 is reduced to one, two orfive, or increased to five. This is not specifically limited in theembodiments of the present invention. In the same way, in some otherembodiments, a plurality of first sliding grooves 5100 may also bedisposed on the first surface 510.

It can be understood that, in this embodiment, the cross sections of thefirst sliding groove 5100 and the second sliding groove 5120 are roughlyin a “trapezoid shape”. Openings of the first sliding groove 5100 andthe second sliding groove 5120 are respectively provided with the firstengagement portion 5102 and the second engagement portion 5122, so as toenable the sliding assembly 52 to slide more smoothly and to avoid thederailment of the sliding assembly 52. In some other embodiments, thefirst sliding groove 5100 and the second sliding groove 5120 may also beset as other suitable structures, such as a strip-shaped groove, or aT-shaped groove.

Specifically, referring to FIG. 22 , the sliding assembly 52 includes aplate body 520, a first sliding member 522 and a second sliding member524. One end of the first sliding member 522 and one end of the secondsliding member 524 are respectively installed on the plate body 520. Theother end of the first sliding member 522 is movably installed in thefirst sliding groove 5100 and the first sliding member 522 is slidablealong the first sliding groove 5100. The other end of the second slidingmember 524 is movably installed in the second sliding groove 5120 andthe second sliding member 524 is slidable along the second slidinggroove 5120. Therefore, the plate body 520 is slidable along the guiderail 51.

The sliding assembly 52 further includes an installation plate 526 and aguiding shaft 528. One end of the second sliding member 524 is fixedlyinstalled on the installation plate 526. The installation plate 526 isinstalled on the plate body 520 by using the guiding shaft 528 and ismovable along the guiding shaft 528 relative to the plate body 520(alternatively, the installation plate 526 can be close to or away fromthe plate body 520 along the guiding shaft 528). Therefore, when thesliding assembly 52 is installed on the guide rail 51 (that is, thefirst sliding member 522 is installed in the first sliding groove 5100and the second sliding member 524 is installed in the second slidinggroove 5120), a distance between the installation plate 526 and theplate body 520 is adjusted by adjusting the guiding shaft 528, so thatan assembly error between the sliding assembly 52 and the guide rail 51may be adjusted, which enables the sliding assembly 52 to slide on theguide rail 51 more smoothly. Certainly, in actual application, the firstsliding member 522 may also be installed on the plate body 520 by usinganother pair of installation plate 526 and guiding shaft 528.Alternatively, the first sliding member 522 and the second slidingmember 524 are both directly fixedly installed on the plate body 520.

The plate body 520 is configured to install the mounting assembly 53 anddrive the mounting assembly 53 to slide along the guide rail 51.Specifically, in this embodiment, the plate body 520 is roughly in an “Lshape”. The first sliding member 522 is installed on one end of theplate body 520. The second sliding member 524 is installed on the otherend of the plate body 520. In the plate body 520, an inner surface ofone end where the first sliding member 522 is installed faces the firstsurface 510. An inner surface of one end where the second sliding member524 is installed faces the second surface 512. Therefore, the firstsliding member 522 can be movably installed in the first sliding groove5100 and the second sliding member 524 can be movably installed in thesecond sliding groove 5120. It can be understood that, in thisembodiment, the plate body 520 adopting the “L shape” can reducecomponents of the sliding assembly 52 and reduce costs. In some otherembodiments, the shape of the plate body 520 may also not be limited tothe “L shape”. For example, the plate body 520 may also be in a flatplate shape. The first sliding member 522 is installed on the plate body520 by using other components.

One side of the plate body on which the first sliding member 522 isinstalled is provided with a scale pointer 523. After the slidingassembly 52 is installed on the guide rail 51, the scale pointer 523 islocated right above the horizontal graduated scale 5104, so as tocalibrate the location of the plate body 520. Optionally, the scalepointer 523 is disposed on a central line of the plate body 520 in ahorizontal direction. Certainly, it can be understood that, in someother embodiments, if the horizontal graduated scale 5104 is disposed onthe second surface 512, the scale pointer 523 is correspondinglydisposed on one side of the plate body 520 where the second slidingmember 524 is installed.

Two opposite sides of the plate body 520 are respectively provided witha first installation groove 5201 and a second installation groove 5202that are configured to install the mounting assembly 53. The firstinstallation groove 5201 and the second installation groove 5202 arealigned in a sliding direction of the plate body 520. In thisembodiment, the first installation groove 5201 and the secondinstallation groove 5202 are disposed to improve a bearing capacity ofthe plate body 520 in a vertical direction, so that the mountingassembly 53 can be fixedly installed on the plate body 520 more firmly.It can be understood that, in some other embodiments, the firstinstallation groove 5201 and the second installation groove 5202 mayalso be omitted.

Moreover, the sliding assembly 52 further includes a locking member 525configured to abut against the guide rail 51, so that the plate body 520is fixed on the guide rail 51.
